History crop

PDX® was founded on a strong belief in the importance and value of Pharmacy in the lives and health of patients.

The National Health Coalition® (NHC) commitment to Pharmacy goes back to the introduction of the first pharmacy system on the IBM PC—pcI professional systems. Founded in 1983 by Ken Hill, R.Ph., pcI professional systems was created to provide basic prescription filling and clinical tasks while solving chain pharmacies’ communication dilemma.

Date 1985b

Established in 1985, PDX, Inc.® has continued to build on this commitment to Pharmacy and patient care. PDX®—whose name has become synonymous with excellence in pharmacy software technology—addressed the requirements of high volume prescription filling and the pressing demands of third party processing. Along with its counterpart, the PDX Host System, the PDX Pharmacy System ensured that the third party requirements of chain clients were in place alongside the essential clinical tasks.

Sixty pharmacy chains—including drug stores, supermarkets, and mass merchants—and more than 350 independent pharmacies in the United States, representing 10,000 individual pharmacies would go on to use PDX® software to fill, bill, and track prescriptions.

Date 1991

Realizing Pharmacy’s need for standardized data, National Health Information Network® (NHIN®) was started in 1991. NHIN® provides its customers with up-to-date and standardized drug file and third party plan information. NHIN® has also become an industry leader in submission and reconciliation service, keeping its customers well below the national average in receivable. NHIN® is currently working with over 300 processors and processing over 14 million claims a month, with a 99.7% payment rate.

Date 1995

In 1995, NHS began designing and built a standard for e–prescriptions, later releasing it to NCPDP. This standard later became known as Script Version 1. NHS released the product in 1995 and installed it in certain Florida independent and chain pharmacies, but the uptake by physicians was so slow that the product was shelved after 18 months. PDX® customers, however, continued to have the ability to accept e–scripts, and the knowledge NHS gained would prove helpful in later system development.

During Chain Link 1995, NHS introduced a prototype of an Internet web engine. Because customers indicated that NHS was considerably ahead of the curve on that product, development was halted. But eventually, electronic retailers like DrugStore.com, Rx.com®, and many others made inroads into the retail pharmacy and healthcare markets. NHS would later resume its development of web-based pharmacy as a key component of its technologies.

Date 1998

Introduced in 1998, NHIN’s disease management software Care Rx® enabled pharmacies to promote complete healthcare through a collaborative effort between the patient, pharmacist, and physician. Based not only on drug therapy but also total lifestyle choices, Care Rx® provides pharmacists with a sophisticated, yet intuitive way to help patients manage their diseases. This holistic approach improves patient care through increased persistency and compliance, as well as total healthcare education.

Date 1999

During one of its busiest years ever—1999—NHS introduced a web engine that pharmacies could use to compete in the online prescription business. The web engine was first installed by an independent pharmacy in West Texas and was later rolled out by other independents and chains such as Wegman’s, Winn–Dixie, Froedtert, and Hadfields. Currently, over 3500 stores use this e–Pharmacy technology which remains a key component of the NHS strategy and the Electronic Pharmacy Record.

In 1999, NHS introduced its version of Central Fill, which was installed by Bergen and California–based Longs Drug Stores at a site that soon began filling up to 15,000 prescriptions a day. Subsequently, Giant Eagle installed Central Fill in Pennsylvania and saw tremendous results.

The year 1999 also brought about the initial design for Workflow™ technology integrated with the PDX® Pharmacy System. As PDX® customers began to look at and respond to the technology, the evolutionary process of Workflow design escalated.

Also in 1999, NHS began building the framework for its next generation pharmacy system. Over the next two years, development of Workflow™ technology continued along with the construction of the next generation pharmacy system.

Date 2001

2001 saw the introduction of eRx Network, a new company founded by NHS and the Lyle family. After developing a completely new architecture, eRx was able to perform load-balancing across two geographically separate co-location facility in the Dallas–Fort Worth metroplex. eRx began with a third party switch, and later introduced pre– and post–edits and the physician–pharmacy interface, which allows prescriptions to electronically flow between physicians and pharmacies. This interface was an enhancement of the products NHS had put into place as early as 1995. eRx Network would be acquired by Emdeon in 2009.

In December 2001, NHS acquired the assets of Rx.com®, including the URL www.rx.com. This acquisition would lay the groundwork to ultimately allow PDX®–NHIN® customers to offer store–based mail order service—complete with fulfillment through Rx.com®.

Date 2002

In 2002, NHS released its Workflow™ and Alternate Site technologies to address increasing prescription volumes and limited staff availability. PDX® Workflow™ technology brings efficiency, accuracy, and flexible options to the prescription filling process.

Date 2005

In 2005, NHS released its national Electronic Pharmacy Record™ technology and ePharmacy Web Engine enabling chains to offer a chain–wide prescription profiles and true chain–wide DUR—years ahead of EHR requirements that would be mandated by the HITECH requirements of ARRA passed by Congress in 2009.

Date 2007

In 2007, NHS released its next generation pharmacy system, the Enterprise Pharmacy System™—a culmination of a six–year, evolutionary project and $100,000,000 investment in technology, created through collaboration with chain pharmacies. EPS™ features an advanced, enterprise–wide workflow engine, central patient record technology, load balancing, and integrated MTM and revenue programs.

Date 2008

In 2008, the RapidFill® implementation of EPS™ was released, giving pharmacies the advanced technology of EPS™ without the segmentation of a full-blown workflow environment.

Date 2009

In 2009, the Electronic Pharmacy Record™ surpassed one billion prescription records and over 72 million active patients from just over 5,000 pharmacies across the United States.

Date 2010

In 2010, EPS® was selected and rolled out by 15 chains and was selected by one of the nation’s largest managed care plans as its pharmacy technology platform of choice.

Date 2016

In 2016, PDX® began offering chains the option to implement Cloud EPS™ from its redundant, fault-tolerant co-location facility. Also debuting in 2016 was our Explore Dx™ business intelligence solution.

2020 1

In 2020, PDX® was acquired by Change Healthcare, a leading independent healthcare technology company with many synergies to the values and goals of PDX.
